Every project I build in the open, with its real state — including the parts that are still in progress.
A high-performance, self-hosted communication platform built for IT labs and strict LAN environments. Cross-platform Flutter client over a PHP/MySQL REST backend, with real-time messaging, rich media and end-to-end encrypted chats.
Runs entirely on your own LAN
Instant messaging & media
Android, iOS & Web
REST API on PHP + MySQL
A study engine for Italian university exams in Calculus I and Linear Algebra. One Rust core — expression AST, parser, differentiation, LaTeX rendering, limits, integrals, series, Taylor expansions, differential equations — behind three front ends: a terminal solver, a local HTTP API and a desktop shell. A question asked in plain Italian comes back as a step-by-step, exam-style solution.
Written entirely in Italian, down to the comments and the knowledge base, because the exam papers it targets are in Italian. Two limits stated up front: the desktop shell needs the WebKitGTK development packages, and the package declares no license on purpose, because the exercises in kb/ derive from course notes whose authorship is not clear.

A multiplayer chess server with a rules engine written from scratch — no chess library. Move generation, castling, en passant, promotion, checkmate and stalemate detection, plus FEN and perft. Ships two clients: a terminal client and a Swing desktop client, over a plain-text TCP protocol.
The most complete project here. Deployed on Railway; a public subdomain is planned but not live yet.

A hardware-accelerated calculator written entirely in C. Custom mathematical evaluator built on a linked-list expression tree, native Wayland tiling support, and a responsive liquid-glass UI rendered with Raylib.
Direct Vulkan/OpenGL rendering
Built for Niri & modern compositors
BODMAS over a linked-list AST
Recomputed every single frame
A desktop music player built around the DJ cue-point concept: walk it, talk it. JavaFX interface with a three-pane layout, a global dark theme and auto-sizing windows, driven by a Maven build.
Interface prototype: the screens, navigation and theming work, but audio playback and library scanning are not implemented yet. No fake data is shipped in place of them.

JDK 21, JavaFX 21, wrapper included
A used-and-new car aggregator for the Italian market, with an RC-car insurance estimate attached to every search. Eight marketplace adapters behind one interface, deterministic fixtures so the app works with no external source, and a pricing model kept out of the code: the insurance engine reads a YAML tariff sheet, so tuning the estimate is a business decision rather than a refactor.
The live sources are not connected, on purpose. Subito, Wallapop and AutoScout24 forbid scraping and run anti-bot protection, so every adapter defaults to supportsLive: false and the app serves fixtures. Wiring a real source means their official API or feed — the registry file says which, per provider, and refuses to parse HTML behind a bot check.
Eight adapters, one interface
Tariff sheet in YAML, not in code

Private repository
Five landing pages, one per project, each on its own subdomain of this site. Every app is a static Next.js export that presents the project, renders its documentation and hands over the source as a tarball taken straight from the branch tip — no zip to maintain, no copy to keep in sync. One monorepo for pushing, five Vercel projects with separate root directories, so a broken config in one does not take the others down.
Nothing is live yet: the five subdomains exist in DNS through the wildcard, and every one of them answers 404 until the matching Vercel project is deployed. The AnalisiLab page deliberately offers no download, because that repository is private.
One per project, one repo
No server, no cold start, no env

Tokens shared with this site
One PostgreSQL schema shared by every service, with a single account table. Twenty tables across five packages: the credentials live in one place, each service owns its tables and joins them with a foreign key, and rotating a password becomes one operation instead of seven — six of which someone forgot.
No application code here: DDL, the apply script and the diagram. Passwords are generated at runtime and handed to psql as variables, so neither the password nor its hash ever reaches a file or the shell history. chess_accounts is the one table that still duplicates credentials, declared rather than hidden, because it verifies with PBKDF2 instead of reading PHP's format.
Five packages, one identity

Private repository
Each project runs on its own. These are the ports they listen on locally, and the subdomains they are meant to reach in production.
A local study tool: the HTTP server binds to 127.0.0.1 only, and the terminal mode needs no server at all.
Plain-text TCP server. A subdomain serves HTTP, and a browser cannot open a raw TCP socket — it would need a web client, which is a separate project.
JavaFX desktop app with a window. A subdomain can only serve HTTP, so there is no version of this project that a URL could reach.
A database schema, not an HTTP service. It is reached with a connection string, so there is no URL that could serve it.
The domain has a wildcard record, so every subdomain above already resolves and answers 404: what is missing is the deployment, not the DNS. Quique is the one that cannot be deployed on the current hosting at all — it needs a host running PHP and MySQL. Cards for private repositories say so instead of linking, so there is nothing on this page to click and fail.
These are the projects I could publish. There are more in progress — send me a message if you want to hear about them.
